A man leaves a dinner party at a relative stranger‘s house to go upstairs, promptly locks himself in a spare room & won‘t come out. The rest of the book centers on three other characters who barely know the man. There are fantastic scenes and great lines scattered throughout and, as usual, Smith can blow your socks off with her way with words. In fact, her use of puns and knock-knock jokes made me chuckle. It‘s a pick but a low one for me.
